46pfl9706 Brightness issues along the left/right edges

Hi. I am experiencing some problems with my 9706. Regardless of source, which could be blu-ray on BDP9600, PC, PS3 or TV I sometimes get these 10-15 cm wide areas along side both edges of the screen which are much brighter than the rest of the picture. I have attached some images of the problem, from TV and blu-ray.

I have not seen this problem reported anywhere else, so is there something wrong with my TV-set? I also have a serious problem with subtitles causing the entire picture to dim up and down, but seems to be a widely described problem, but I am pretty sure the last software update made it worse on my set. the same goes for the banding/dirty screen effect which seems to be apparent on these series.

So, what could be the cause of this problem? It seems to be affected by the perfect contrast setting. It also gets worse if I move slightly sideways away from the center of the screen, to either side.

That is a known issue present on all Philips 2011 9 series. Although you are experiencing very severe case of it judging from your photos. On my 9606 there is very subtle edge light bleed on, but nowhere near what I see on your 9706. And it is noticeable only on dark scenes.
You can take your time and read through the threads discussing SW on 2011 9 series. With the last 2 versions(14.98&14.101) changen in local dimming and dynamic backlight operation were introduced, leading to many users unhappy with TV performance. It appear that one have to revise TV settings with of contrast, brightness and gamma to get the picture back to the previous level. Picture with 14.101 appear more bright and black is not black as it is used to be. Read the corresponding thread for more info.
